Mencionar 3 utilidades dos cactos.

Cacti are used for:

1. Decorating and Landscaping - as houseplants, in dry gardens, or, even as a fence.

2. Edible Fruit Producing - such as Prickly Pear, Hylocereus, Dragon fruit.

3. Psychoactive uses - the Peyote, Lophophora williamsii, is a well-known psychoactive agent used by Native Americans in southwestern United States.

4. Host for bugs - the Opuntia is also used as a host for cochineal bugs for the Cochineal dye industry.

5. Food - Nopal cactus has been a staple food and base for beverages in Mexican culture for centuries.

6. Emergency water source - Some cactus can serve as an emergency water source, but be careful as you can get diarrhea causing further dehydration.

Em que região há mais quantidade de cactos? Por quê?

Cacti can adapt very well to dry climate or rocky terrain like deserts or mountains, but they can thrive in jungles. They prefer a hot, dry climate, not a humid, hot climate as popular myth suggests. The fact that they also thrive on sandy/rock soil is because the way water doesn’t pool near or on them and the nutrients the soil is rich with.
